I currently have a Reseller account with HostGator, and my personal experience is OK. Support questions are usually answered within about an hour and technical problems have been fixed in a competent way.
Their low-budget plan is called "Hatchling"; it currently offers the (insane) amounts of 350GB space and 3000GB/month transfer for $6.95 per month - but you must pay for a whole year (or get a $4.95/month deal by paying for 3 years upfront). With the other plans, which begin at $9.95 per month, you also have the option to pay monthly. There are no setup fees.
The "Hatchling" plan allows you to have just one domain; but all other accounts come with unlimited domain allowance.
I have seen several posts at WebHostingTalk.com, a leading web hosting forum, from people who express their spontaneous happiness about the service level of this company. It is unusual to find so much genuine praise for a budget web hosting provider, since people are much more likely to post negatives than positives.
One example of a very recent post on HostGator:
..."Wanted 24/7 telephone support-got it. Can't remember the last time the site was down. Have absolutely no complaints and am glad to have made the switch to Gator"...
As you may guess from the company name, they are located in Florida (Boca Raton). However, their data center is situated in Dallas, Texas and administered by The Planet. HostGator has been in business since 2002 and offers a range of shared, dedicated, and reseller plans.
All accounts are e-commerce enabled; offering shared SSL support (private SSL available with more advanced plan); and three different shopping cart systems. You get phone support 24/7, and also support via e-mail and live chat.
As is the norm in the hosting industry, Host Gator web hosting offers a 30-day money back guarantee.
All plans include access to the Fantastico script collection, which lets you install many useful web site functions, such as forums and message boards, with one click.
